Black screen on LG LCD TV

Hi i have an LG model pdp42G1 LCD TV. When i turn on my Tv it gives a green light but Black screen. the light becomes red but it doesn't blink. I checked the power board for bad caps but didn't find any on the whole TV. Then i looked for the blue capacitors to see if there was a bad one but also good. i don't know what to do now.

hello, amigo if the all the caps are godd then you have to replace the power supply board. don't try to fix it this is not an easy task. you are looking at almost $200.00 with tax an shipping. just go to google and type your tv model # and ask for the power supply board or just look for the part# on the board itself. good luck
